WATER-HEATER.

Specification of Letters Patent.

Patented Feb. 111, 11919.

Application filed August 17, 1916. Serial No. 115,380.

Be it known that I, JosEPH G. BECK- -MANN, a citizen of the UnitedStates, and

resident of St. Louis, Missouri, have 1nvente'd certain new and usefulImprovements in Water-Heaters, of which the following is a specificationcontaining a full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention relates to improvements in water'heaters, designedprimarily for domestic purposes, and my improvements are especiallydirected to the construction of the boiler or water heating body and itscasing or shell, the object of my invention being to construct a boilerand to provide a casing therefor and arrange same to be heated by a gasor other vapor burner which will heat a maximum volume of water at arelatively high temperature in a minimum of time and without the usualpounding due to improper circulation.

With the above purposes in view, my 1nvention consists in certain noveldetails of the construction and arrangement of parts hereinafter fully,clearly and concisely set forthin my specification, pointed out 1n myclaims and illustrated by the accompanying drawing, in which Figure 1 isan elevation of a devlce embodylng my improvements, with the door of thecasing in an open positlon;

Fig, 2 1S a vertical sectional elevation of the casing or shell havingthe boiler and burners removed and taken at right angles to Fig. 1;

Fig. 3 is a sectional plan vlew taken on the line 33 of Fig. 1, with thedoor of the casing in a closed posltion; v

Fig. 4 is an enlarged fragmental sectlonal elevation illustrating theconstruction of the walls of the boiler; and

Fig. 5 is a sectional elevat on of the base portion of the casing,showing the means for attaching a burner to the bottom of the base.

- when the device is set up rests upon the union and thus supports saidbase 11.

Arislng from the upper end of the base is a flange 14 and extendingupwardly beyond said flange is a number of ears 15, one only of WlllChis shown in Fig. 2. The flange 14 1s inset from the outer periphery ofthe base formlng a shoulder 16, which shoulder constitutes a support forthe casing or shell of the boiler.

By preference the casing comprises two sections of semi-cylindricalformation, the one section 17 arranged to rest upon the shoulder 16 ofthe base and be secured to, the base by means of bolts extended throughopenlngs formed in the section 17 and through the ears 15, the othersection 18 of the casing being hinged to the base, the lowermost hingecomprising a perforated lntegral extension 19 of the base an an integraloutstanding lug 20 having a pin 21, as clearly shown in Flg. l.

The reference numeral 22 designates the cap of the casing, which isprovided with a flange 23 corresponding with the flange 14 of the base,except for its inversion when assembled, and with an outstandingshoulder 24 arranged to snugly 'fit the upper margins of the sections 17and 18 of the casing. Like the base 11, the cap 22 is provided with ears25 whereby to secure the section 17 of the casing to the cap. Formedcentrally through the cap is an opening 26 through which a pipe 27extends for connecting the upper end of the boiler 10 to a water tank orthe like (not shown).

By preference I employ a shortnipple 28 (shown only by dotted lines inFig. 1) which connects directly with the boiler 10 and extends throughthe opening 26 and is connected with the pipe 27 by a union 29. Byreason of the union 29 and the union 8, I am enabled to facilitate theassembling of the casing elements by exerting pressure on the cap andbase by saiclunions thus holding the casing elements assembled duringtheir connection by the bolts 15 securing the one shell section to thebase and the bolts connecting the said shell section with the cap.

Formed through the cap to one side of the opening 26 there is an opening30, and surrounding the opening is an outstanding bead or collar 31 forconnection with a flue (not shown) to carry of]? the unconsumed gases,vapors, or other odors arising from the casing.

Extending laterally from the cap 22 is an ear 32, constituting a portionof the hinge connection between the section 18 or door of the casing andthe cap, the other portion of the said hinge connection being a lug 33,the companion of the lug 20 hereinbefore described.

In order to secure the door in a closed position, I provide the section17 of the casing with an integral outstanding car 34' and the section 18or door with an integral outstanding hooked element or latch 35, whichin closing the door automatically rides over the ear 34 and seatsthereover to lock the door, it being necessary for opening the door torelease the hinged element 35 by elevating it over and from the car 34.The boiler lO is formed preferably by casting as an integral unitcomprising two tubular columns 36 and 37, the respective ends of whichare united by return bends 38 and 39, the columns of said bends takingthe form of an elongated 0.

The inner surface, as clearly shown in Fig. 4, is undulated in order topresent to the water therein a maximum of surface as well as a retardinginfluence. The outer surfaces of the columns, as well as the returnbends of the boiler, are provided with spaced annular outstanding fins40, certain of which, extending between the columns, are integrallyunited whereby to lend rigidity to the boiler as well as to constituteadditional means to retard and circuitously deflect the heat units intheir traverse of the casing. Each of these fins 40 constitutes aheat-absorbing body, and it is obvious that when the fins are heatedthey retain heat for a considerable period of time, thereby economizin-gthe heating of successive quantities of water.

The fins on the vertical columns are arranged at right angles to theaxes of the columns, while the fins on the return bends 38 and 39 are inradial disposition.

In. addition to the fins as means for defleeting the traverse of the hotgases or vapors, I form integrally with the sections 17 and 18 of thecasing deflectors 41 and 42, each of which has an area of substantiallyone-half (4) the diameter of the easing, and each being provided withnotches 43 to surround the columns of the boiler.

Formed integrally with the cap and extending downwardly therefrom in avertical position and to one side of the flue opening 30 is a deflector44, the lowermost end of which approximates the fins 40 of the boiler.Extended upwardly through the open side of the base 11 is a pair ofvapor burners 45, preferably of the Bunsen type, each burner beingprovided with an 'earf, 46 for. connection with the bottom 12 of "thebase, as clearly shown in Fig. 5. These burners are each equipped withmixers 47 and valves 48, the specific structures of which form no partof my invention. The valves are connected by means of a Y-fitting 49 tothe gas service pipe 50, a portion only of which is shown in Fig. 1. Itwill be obvious from this showing that when the burners are ignited theflames therefrom will produce in a minimum of time a great volume ofheat units which rise to the deflector 42 and contact the entire surfaceof the boiler or water heating body, including all of the fins 40.Meeting the deflector 42, the heat units are all deflected to one sideof the casing, thereby retarding their' motion. The heat units then riseand are then shifted in their course by the deflector 41, where theyagain rise and are retarded by the deflector 44 before reaching the flueopening 30. In this manner there is produced a relatively long traversefor the products of combustion and hot gases through the casing, andthus cause the heat units to intimately hug the Walls of the boiler andbe absorbed by the fins thereof.

The water is fed to the boiler, through the pipe 9, and by reason of theincreased capacity of the column of the boiler over the pipe 9, the flowof water is much slower through said columns than through itssupply pipe9, and by reason of the undulated surface of the heat absorbing fins,the water is heated in a rapid manner and in a considerable volume. Inorder that there be a minimum of escape of heat units at the joints ofthe casing, I have provided the lap-flanges 51, as clearly shown in Fig.3.

It is to be observed that the upper faces of all of the fins on thecolumns proper are arranged horizontally, whereby to collect water ofcondensation and hold such water to prevent it from dropping through thecasing and soiling the floor or foundation beneath the heater, therebydispensing with a drip pan.

Having thus described my invention, what I claim as new therein anddesire to secureby Letters Patent of the United States, is:

1. A boiler comprising twin columns and integral return bends unitingthe columns, outstanding fins on the outer surface of the boiler, and anundulated surface within the boiler.

2. A boiler comprising twin columns, integrally united by reverse bends,a water inlet in the one bend and a water outlet in the other bend, andan undulated surface within the boiler.

3. A boiler constructed as an integral unit, comprising tubular columns,united by reverse bends, outstanding fins on said columns and reversebends, certain of which fins between said columns are connected to lendrigidity to the boiler and to retard and deflect a heating medium andmeans whereby the boiler may be connected with water inlet and outletpipes.

4. In combination with a water heating body, comprising tubular columnsunited by reverse bends, means for connection with water inlet andoutlet pipes and heat absorbing fins, certain of which fins between saidcolumns are connected to lend rigidity to the body and to serve asdeflectors for a heating medium, a casing comprising hinged sectionsserving as side walls therefor, a cap and a base, a source of heatextended through said base, there being an outlet for the heat in saidcap, deflectors carried by said hinged sections and notched toaccommodate said columns and a deflector carried by the cap in advanceof said outlet with respect to the course of the heat.

In testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
